Overview Holder and BIM: Some Basic Philosophies Highlight Some Experiences Benefits, Challenges, and Lessons Learned Updates - Some Industry Ongoing Efforts
Holder and BIM Basic Philosophies: A question of when, not if! Only for Gehry-esque type projects? BIM Projects fall into 1 of 2 categories 1. Designed (in 3D) 2. Conversion (to 3D) To date, no Gehry-esque ; only Conversions
Virtual Design and Construction Building Information Modeling BIM Update Excerpted From Internal Holder Presentation
WHAT WE RE DOING WORKS FINE!! Why Change? GET REAL. WE RE IN THE FIELD. WE RE BUILDERS!!
Why Change? HOW S THAT WORKING FOR YOU NOW??? WOULD YOU RATHER FIND OUT IT S WRONG BEFORE YOU GET OUT IN THE FIELD, OR AFTER??!
What Is BIM? Building Information Modeling Virtual Design & Construction Object Based. Parametric.

BIM Benefits 1. Visualization Infinite cut sections/drawings 2. Conflict, Interference and Collision Detection 3. Scheduling and Phasing What if s 4. Sequencing, Workflow, Safety and Site Logistics 5. "Smart Drawings": Estimating and Quantity Extraction 6. Scope Clarification, Trade Coordination and Options Analysis 7. As-Builts, Facility Management, and BD uses and many others we are still discovering!
Examples of Benefits Options Analysis (Value Engineering) Scope Reconciliation (comparisons) Virtual Mock-Ups Brick Precast
Progressive Data Center Phases started / used: Conversion from 2D What was modeled: Entire Project Who did the modeling: Outsourced

Coordination
Making the Business Case 2D HVAC Plan 3D Overhead Rendering of Areaway 2D Pipe Plan Issue: Issue: Generator exhaust pipe and battery room exhaust duct conflict in areaway. Result: Duct penetrations through precast wall panels were relocated and generator exhaust pipe routing was modified in field. Potential Cost Savings = $60,000 Photo of Installation
Challenges / Lessons Learned Conversions on Fast-Tracked Projects Level of Granularity, decide early Prefabrication: Higher quality, lower cost File Sharing: FTP Site (two way)
Challenges / Lessons Learned Trusting the Data (side-by-side estimates) Visualization is the low hanging fruit The 3 Fears ( for our convenience ) Changing our Everyday Processes
Update on Other Ongoing Efforts CURT OAEC Productivity (AGC Report) AGC PIAC s BIM Taskforce AIA / AGC Joint Committee Survey One of the limitations of 2D drawings is that only people can read them. Chuck Eastman, GA Tech
